Preheat oven to 200°C and line a baking tray with parchment paper.
Add the chickpeas, oil and seasonings in a bowl and toss.
Spread onto the baking tray and bake for 25-30 minutes or until lightly golden.
In the meantime, in a small bowl whisk together the tahini, lemon juice, salt and sweet chilli sauce.
Then add the water to adjust the consistency if needed until its pourable.
Add the lettuce, avocado, cucumber, onion and chickpeas to a salad bowl and pour over the dressing and toss.
